This two ply ESD mat is a static dissipative industrial grade elastomer designed for use on tables and other grounded work bench surfaces. Unique features allow conformance to the most stringent ESD and lead-free requirements: low out-gasing and VOC, withstands high temperatures, solder, flux and harsh chemicals, .05 second decay time. This chemically cross linked material will not lose electrical properties and has different electrical resistance on both surfaces: 108Ω/sq. on colored side, 105Ω/sq. on black side. Durable and rigid laminates are 2mm thick so it will lay flat and won't curl. Available in Royal Blue, Light Blue, Dark Gray and highly visible green which indicates workstation is lead-free.
